Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
6-Bromo-2,3-indolinedione 6-Bromoindole-2,3-dione 6-Bromoisatin 6326-79-0 B2424 (CAS 6326-79-0) is a high-purity analytical reference standard with the molecular formula C8H10BrNO2 and a molecular weight of 232.07 g/mol.
The molecular framework of 6-Bromo-2,3-indolinedione 6-Bromoindole-2,3-dione 6-Bromoisatin 6326-79-0 B2424 (C8H10BrNO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
